Hmmm, this is becoming difficult ..

I have added into the engine the custom hook and understand how that will work. 
 The issue is how can a single NIC use two different bridges ?  Example with 
OVS would be that one requires:

em1 -+ ovirtmgmt (bridge) -> management IP (public)
     + ovs       (bridge) -> firewall IP (public)
                                |
                                + vlan 1
                                + vlan 2

this works fine when using OVS and KVM, without oVirt, so there must be a way 
to hook the two together without a Neutron appliance.

Any thoughts ? Thanks, Phil.

Once you start to use the vdsm-hook-extnet, all that you need to do is
to replace the libvirt-side definition of the "external network". This
may well be an OpenVSwitch-based network e.g.
